Chapter 2: Installation and Hardware Setup Installing the SAS6160 Switch LSISAS6160 SAS Switch User Guide

2.2.1	SAS6160 Connectors	All 16 connectors on the SAS6160 switch accept standard passive SAS cabling. The
		connectors at port 0 and port 2 are active, which allows longer cable lengths when
		using active SAS cabling. See Chapter 1 for an explanation of SAS connectors and
		cables.
		Table 1:	SAS Cable Lengths
		Connectors			Cable Type	Min. Length	Max. Length
		1 and 3 - 15			Passive	0.5 m	10 m
		0 and 2 only			Active	—	25 m
					Passive	0.5 m	10 m
2.2.2	SAS6160 LEDs	The following table shows how to interpret the LEDs for the system, the phys, the
		power supply module, and the Ethernet (RJ-45) connector. The LEDs in the RJ-45
		connector are built into the left and right corners of the connector.
		Table 2:	LED Modes
		LED Name		Color		Meaning
		Power (P12V)		Green	12V power is present on the board.
		SAS Activity		Green	Blinks with activity on at least one of the four PHYs in the x4 SAS
					port.
		SAS Fault		Amber	At least one of the PHYs in the x4 SAS port is down.
		Ethernet		Amber	Link is active. Blinks with activity.
		Link/Activity
		Ethernet Link		Green	Rate of link.
		Rate			Off = 10 Mb/s.
					On = 100 Mb/s.

2.3Installing the SAS6160

Switch

WARNING: To prevent the SAS6160 switch from overheating, do not operate it in an environment that exceeds the maximum recommended ambient temperature of 50 ºC (122 ºF).

When installing the switch, consider the following information:

„The acceptable temperature and humidity operating ranges for installation and operation of the switch are as follows:

—Temperature Range: 5–50 ºC (dry bulb)

—Relative Humidity Range: 5%–90% noncondensing

—Maximum Dew Point Temperature: 32 ºC

„Install the SAS6160 switch in a site free from strong electromagnetic field generators (such as motors), vibration, and dust.

„Allow some space at the back of the switch (where the fans intake air) for proper ventilation.

„The AC power adapter is rated at 100 V to 240 V, and 50 Hz to 60 Hz.
